A friend and I have been researching a school that was destroyed by fire in 1880 and the area was turned into a farm field. We knew the approximate location but took a lot of walking to find it.
I started detecting the site with my DFX and Ultimate 13 coil and was rewarded with this Eagle Breastplate, Regulation 1826 Pattern (Maker Marked W.H. Smith / Brooklyn). It’s not in the best shape but to me it’s priceless.
